J2 - Thumbwheel Multiplexer Port (JTHW Port)
The Thumbwheel Multiplexer Port, or Multiplexer Port, on the JTHW connector has eight input lines and
eight output lines. The output lines can be used to multiplex large numbers of inputs and outputs on the
port, and Delta Tau provides accessory boards and software structures (special M-variable definitions) to
capitalize on this feature. Up to 32 of the multiplexed I/O boards may be daisy-chained on the port, in
any combination.

J7 - General-Purpose Digital Inputs and Outputs (JOPT Port)
Acc-2P’s JOPT connector provides eight general-purpose digital inputs and eight general-purpose digital
outputs. Each input and each output has its own corresponding ground pin in the opposite row. The 34-
pin connector was designed for easy interface to OPTO-22 or equivalent optically isolated I/O modules.
Delta Tau’s Acc-21F is a six-foot cable for this purpose.

TB1 – Power Supply Terminal Block (JPWR Connector)
In almost in all cases the PMAC2A PC/104 will be powered from the PC/104 bus when it is installed in a
host computer’s bus, or from the JMACH1 connector. This terminal block may be used as an alternative
power supply connector or to easily measure the voltages applied to the board.
